time_conv

bio_rtd.utils.convolution.time_conv(dt, c_in, rtd, c_equilibration=None, logger=None)[source]

Perform time convolution

First time-point of c_in and ‘c_rtd’ is at t == 0 (and not at t == dt). Convolution is applied to all columns (= species) of the c_in

Parameters

  • dt (float) – Time step.

  • c_in (np.ndarray) – Starting concentration profile for each specie

  • rtd (ndarray) – Residence time distribution (= unit impulse response)

  • c_equilibration (Optional[ndarray]) – Initial concentrations of species inside the void volume of the unit operation. E. g. the composition of equilibration buffer for flow-through column.

  • logger (Optional[RtdLogger]) – Logger can be passed from unit operations

Returns

Final concentration profile for each specie

Return type

np.ndarray

Return type

ndarray
